How to access rear washer pipe in Front Passenger Footwell

When it was cold i think i somehow managed to make one of the washer pipe quick fit connectors pop open.

I am having great difficulty in finding it. When the rear washer is switched on water pours down from the front NS wheel arch on to the footwell carpet. Ive had the trim off at the side of the glovebox, removed glovebox, and can see the pip, but its leaking higher up and I cant see how to access it.

Ive also tried jacking the car up and removing the wheel arch liner, and the under body trim at the front, but the washer pipe seems to be hidden somewhere that I cant see

Anyone got any ideas where it might have come apart and how the bloody hell I can access it to reconnect???

Thanks in advance
